RADIATOR-CELL SECTION.

Specification of Letters Patent.

Application led November 1, 1912.

To cttw/tom, yit may conce/ML Be itknown that we, HERBERT CHAMPION HannIsoN and EMIL CARL Fnnnnnrcit Srnnromnrr, subjects of the Kings of Great Britain and Denmark, respectively, residing at Lockport, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Radiator'- Cell Sections; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to the construction of radiator cells, and has for its object to provide a structure for such cells which will be simple and economical tomanufacture, one which will be compact and light, and which will have longer water courses'than it has been possible to provide in analogous cells that have been heretofore proposed.

To these ends the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the Views:-,Figure 1 is an elevational View partly in section of a radiator built inaccordance with the invention; Fig. 2 is a sectional perspective View of a ortion of the cells made in accordance with t e invention; and, Fig. 3 is an enlarged detail view in section of a pair of unit cells showing the zigzagwater course between the same.

1 indicates any suitable framework of the radiator, 2 the upper water chamber pr0- vided with the plate 3 having the water passages 4 through which water passes to the zigzag passages 5 between the cells G, as will be readily understood from the drawings. ln constructingthe cells 6, we preferably take a strip of metal such as 7, fold it upon itself to form a partition or plait 8, thereupon bend it outwardly at an angle of 120 as at the point 9, and at the point 10 a`distance equal to the length of the partition 8 we again bend the metal inwardly at an angle of 12()o to itself, while at the point 11 at a distance from the point 10 equal to the length of the partition or plait 8 We again bend the metal upon itself to form another plait or partition 8. The process is repeated until sufficient partitions 8 are Iatentod Sept. 16, 1913,

the plait 8, and the process continued until` sutlioient partitions 17 are formed to make up the alternate divisions of a cell unit. The partitions -S and 17 are assembled in staggered relation, as indicated in the drawings, and at the midpositions between the said partitions S and 17, we preferably provide indentations 18 in the sides of the metal plates into which the extreme edges of the partitions 8 and 17 rest. The respective sides of the unit of cells thus formed may be made of a single sheet of material, as above indicated, or of course, they may be made of separate sheets as desired. lVhen said sides are lformed of a single sheet, as illustrated in Fig. 3, the extreme ends 19 and 20 of the sheet are folded upon themselves, as indicated, to form a flat surface to which the plate 21 of the radiator proper may be secured. lVhen the said sides are made of two separate sheets of mate 'ial, the fiat surface 13 will be formed of overlapping parts in all respects the same as the parts 19 and 2() just disclosed, and in either case the plate 3 will be attached to the said member 13 by solder, or otherwise. A. radiator cell unit 22 being thus produced, a second cell unit 23 is formed in precisely the same manner, and is located between the plates 3 and 21 at a sulieieut distance from the unit 22 to form the zigzag water passage 5, a's shown.

It is an important feature of our invention that the In'ojecting portions 18 of the one unitl come opposite the retreating portions 21 ot' the other unit, so that the cells are self-alining when assembled, and therefore, render this step in the manufacture of the radiator very inexpensive. lt is further evidcnt that the zigzag water passage 5 is longer than any straight passage could possibly be between the plates 3 and 2l, and that therefore, the water is subjected to a greater cooling action than would be the case with a straight passage. Further, the

indentations 1S into which the partitions 8 and 17 fit, serve to brace the entire Structure and to render the same unusually strong when the weight of metal is considered. Any suitable separating means, such as a zigzag plate 5, may be employed at the eX- treme edges of the cell plates 7.

It is obvious that those skilled in the art may `1vary the arrangement of parts and the details of construction without departing from the spirit of our invent/ion, and therefore, We do not wish to be limited to ythe above disclosure except as may be required by the claims. One such obvious change would be eiected by merely dipping the front and back of the cellular core in solder to form a rigid structure, and then suitably securing said core in the frame' 1 without eilnploying any top and bottom plates 3 at a l.

What we claim is 1. In a radiator the combination of a plurality ofcell units each having zigzag eX- terior walls forming a zigzag Water passage between contiguous pairs, each unit comprising walls bent upon themselves to form opposing partitions located in a staggered relation to each other, and said walls being o bent outwardly from said partitions and inwardly between the same to form quadrilateral cells, substantially as described.

and inwardly between the same to form` quadrilateral cells, substantially as described.

In testimony whereof, we aiiix our signatures, in presence of two witnesses.
